<h1>Extending the Kubernetes API with the aggregation layer</h1>



<p>The aggregation layer allows Kubernetes to be extended with additional APIs, beyond what is offered by the core Kubernetes APIs.</p>









<ul id="markdown-toc">










<li><a href="../../../api-extension/apiserver-aggregation.1#overview">Overview</a></li>




















<li><a href="../../../api-extension/apiserver-aggregation.1#what-s-next">What's next</a></li>



</ul>


<h2 id="overview">Overview</h2>

<p>The aggregation layer enables installing additional Kubernetes-style APIs in your cluster. These can either be pre-built, existing 3rd party solutions, such as <a href="https://github.com/kubernetes-incubator/service-catalog/blob/master/README.md" target="_blank">service-catalog</a>, or user-created APIs like <a href="https://github.com/kubernetes-incubator/apiserver-builder/blob/master/README.md" target="_blank">apiserver-builder</a>, which can get you started.</p>

<p>In 1.7 the aggregation layer runs in-process with the kube-apiserver. Until an extension resource is registered, the aggregation layer will do nothing. To register an API, users must add an APIService object, which &ldquo;claims&rdquo; the URL path in the Kubernetes API. At that point, the aggregation layer will proxy anything sent to that API path (e.g. /apis/myextension.mycompany.io/v1/…) to the registered APIService.</p>

<p>Ordinarily, the APIService will be implemented by an <em>extension-apiserver</em> in a pod running in the cluster. This extension-apiserver will normally need to be paired with one or more controllers if active management of the added resources is needed. As a result, the apiserver-builder will actually provide a skeleton for both. As another example, when the service-catalog is installed, it provides both the extension-apiserver and controller for the services it provides.</p>
